At least not on my side: I got the update this morning, but compiling:

\documentclass{article}

\begin{document}
Something
\localleftbox{Hello}
%\localrightbox{Goodbye} % This one will trigger the error too.

Something
\end{document}

gives me this:

This is LuaTeX, Version 1.10.0 (TeX Live 2019)
 restricted system commands enabled.

Of course, the issue is the same with luatex.
